What is a multi-pole DC switch-disconnector?

A multi-pole DC switch-disconnector is a device designed to perform safe switching, disconnection and isolation of direct current in photovoltaic installations.

Multi-pole configurations enable the management of different electrical schemes in solar applications, improving design flexibility and facilitating integration into DC electrical panels and renewable energy systems.

In large-scale photovoltaic installations, particularly in solar plants with photovoltaic trackers, the use of multi-pole switch-disconnectors is essential to ensure safety, maintenance and operational continuity.

New installation options for multi-pole DC switch-disconnectors

With this product range extension, the F1 Series multi-pole DC switch-disconnectors are available in different types of mounting to facilitate integration into any photovoltaic design.

The new range includes solutions for:

DIN rail mounting
Rear-of-panel mounting
Enclosure backplate installation

This variety of formats allows the switch-disconnector to be adapted to the specific requirements of each application, optimising available space and simplifying installation in DC protection panels, inverters and systems with solar trackers.

Where are the new F1 Series multi-pole used?

The new multi-pole versions have been developed for applications such as:

Photovoltaic trackers
DC protection panels
Solar inverters
Combiner boxes
Utility-scale photovoltaic systems
